摘　　要：春玉米套作夏大豆是带状复合种植的重要栽培模式,可有效提高土地利用率,在种植玉米的地块上增收一季大豆。为筛选出适合西南丘陵山地大豆玉米带状复合种植模式的玉米品种,收集了10个玉米新品种,进行大豆玉米带状复合种植模式下玉米品种筛选试验,对各玉米品种的株高、株型、倒伏率、百粒重、穗粒数、产量和大豆的倒伏率、叶片叶绿素相对含量(SPAD值)、百粒重、单株粒数和产量进行了比较分析。结果表明,株型较好、抗倒伏且产量较高的玉米品种为仲玉3号、绵单53和科茂918;同时,通过相关性分析发现,玉米株高较矮可间接增加大豆产量;通过生产效益分析可知,绵单53和仲玉3号适宜大豆玉米带状复合种植模式,在生产中应用可获得较大收益。Spring corn strip intercropping with summer soybean is an important cultivation mode of compound planting,which can effectively improve land use efficiency and harvest extra soybean in the corn field.In order to select corn varieties suitable for strip intercropping mode of soybean and corn in hilly and mountainous areas in southwestern China,10 new corn varieties were collected for corn variety screening test under strip intercropping mode of soybean and corn.The plant height,plant type,lodging rate,100-grain weight,grain number per ear,yield of corn varieties were compared and analyzed,as well as the lodging rate,leaf chlorophyll relative content(SPAD value),100-grain weight,grain number per plant and yield of soybean varieties.The results showed that the corn varieties with good plant type,lodging resistance and high yield were Zhongyu 3,Miandan 53 and Kemao 918;at the same time,through correlation analysis,it was found that shorter corn plant height could indirectly increase soybean yield;according to the analysis of production benefits,Miandan 53 and Zhongyu 3 were suitable for the strip intercropping mode of soybean and corn,which could obtain great benefits in production.
